Any questions?

Does it come with a warranty?

All parts are individually warrantied by the company who produces the part. Please look into each warranty terms and service.

What happens if I don't like it?

Customer satisfaction is our #1 priority so if you are unhappy with something in the build let us know and we can either recommend a part that will better suite your needs or look at more tuning options to meet your expectations.

How fast is shipping?

Shipping will depend on availability of parts. While we stock our most commonly sold parts we do not stock all parts. If a part is on back order or has a lead time we will communicate with you through the whole process so your are not left wondering why a part hasn't shipped yet.

Once a part has been installed we can no longer take the part back.

Returns and Cancelations are subject to a restocking fee.

For our pre made builds sales are final so please contact prior to purchasing to make sure the build meets your expectations, its easier to adjust the build before the purchase rather than after.
